Casio XJ-H1750 Projectorwith LED/Laser Hybrid Light Engine

No color mode settings for brightest modes. The non-Eco modes don't have any color presets, so you have to either stay with the default setting, or adjust the color settings manually.

Rainbow artifacts. Rainbow artifacts are always a potential issue for single-chip DLP projectors. With the XJ-H1750, they show up infrequently enough with data that even those who see them easily shouldn't find them bothersome. They show up more often with video, which is typical, but less often than with many DLP projectors, making this only a moderate issue even for video. Those who are most sensitive to seeing DLP rainbows may find them annoying, but most people probably won't.

Limited 3D. The XJ-H1750's 3D is even more limited than with most 3D-ready projectors. As with most, its key shortcoming is the need to buy enough pairs of DLP-Link glasses for your audience, at $70 or more each. Unlike many, however, it supports 3D only over a VGA connection. This means you can't connect through a video converter to show 3D from a Blu-ray player, and you're limited to an analog connection even with a computer.

Conclusion

The Casio XJ-H1750 is a little different from most projectors, with most of the differences in its favor. The hybrid light source, with its mercury-free design and 20,000 hour lifetime, offers ecological benefits and lowers cost of ownership. It also helps that Casio backs up the light source with the extraordinarily long, 5-year or 10,000 hour warranty, the best in the business.

Adding to potential ecological and economic benefits are the seven different levels of brightness without having to change color mode. Instead, for the Eco modes at least, you can pick the most suitable color preset first, and then pick the brightness most appropriate for the lighting conditions.

The projector also scores well on more standard issues. It earns points for its excellent data image quality and usable video quality, plus the reasonably good audio quality and volume. Similarly, the 3700 lumen measured brightness is a solid 93% of the 4000 lumen claim, and easily enough to throw a bright image at a size suitable for a mid-size conference room or classroom. Whether you're drawn in by the ecological benefits, or just want a capable projector, the Casio XJ-H1750 is a particularly impressive beast.

Sheesh! Why are we dragging our heels so hard on the resolution, going up half a step at a time at big cost? By the time projectors make it you'll be able to walk into Home Depot and leave with a 4x8 ft flat screen for ninety bucks.

WOW 4000 brightness with 20000 hrs life its a good deal if its offered with short thoro lense of .5 or less lense ratio and Native resolution Wxga with little improved uniformity lets say 85% I would love you use it for my control room applications.

There is a great difference between a laser beam bounced off a mirror and directly at your eye vs. projected light spread across a 80" or so piece of vinyl with a sprayed particle coating. These projectors are just bright enough to see a picture, and although they are improving... they are hardly bright enough to burn your retina... I would however suggest backing a little further away from your microwave while it is active... :)

I wonder if these lasers could harm the eyes as at the end of the day they are [%#^&*&*@] burning lasers.What they can do is amply demonstrated on many youtube videos.What we are seeing is reflected laser light.Isn't it ?

Wow, great leap for Casio! Now, bump up the lumens to 5k, and make it HD and I'm in for 4 or 5 units.

But this model should be great for a large variety of uses right now!
